NAME
       protocols - protocol name data base

DESCRIPTION
       The  protocols  file contains information regarding the known protocols used in the DARPA Internet.  For each protocol a single line should
       be present with the following information:

       official protocol name
       protocol number
       aliases

       Items are separated by any number of blanks and/or tab characters.  A ``#'' indicates the beginning of a comment; characters up to the  end
       of the line are not interpreted by routines which search the file.

       Protocol names may contain any printable character other than a field delimiter, newline, or comment character.

FILES
       /etc/protocols

SEE ALSO
       getprotoent(3N)

BUGS
       A name server should be used instead of a static file.
